LEARN ABOUT THIS INITIATIVE

Overview

On July 13, 2017, the Commission issued the Order Instituting this Rulemaking (OIR) in order to consider a variety of refinements to the interconnection of distributed energy resources under Electric Tariff Rule 21 of Pacific Gas and Electric Company, San Diego Gas & Electric Company, and Southern California Edison Company (the Utilities), and the equivalent tariff rules of the small and multi-jurisdictional electric utilities.  The Scoping Memo directs Working Group Four to develop proposals to address four issues related to streamlining and improving the interconnection process. The working group is to submit a final report after the issues have been workshopped in 2020See the Scoping Memo for the full scoping proposed for Working Group Four. The report shall recommend proposals to address the following issues:

  • Issue 18: Should the Commission adopt changes to anti-islanding screen parameters to reflect research on islanding risks when using UL 1741-certified inverters in order to avoid unnecessary mitigations? If yes, what should those changes entail?
  • Issue 19: Should the Commission adopt streamlined interconnection procedures (e.g. standard configurations eligible for expedited review) to facilitate implementation of California Zero Net Energy building codes and, if so, what should those procedures entail?
  • Issue 29: Should the Commission establish a forum, either within this proceeding or externally to develop interconnection safety standards to address safety and environmental risks as the interconnection of distributed energy resources devices grows
  • Issue F: What interconnection rules should the Commission adopt to account for the ability of DERMS and aggregator commands to address operational flexibility need.
